Quick-detach suppressor adapter

ABSTRACT

A muzzle mounted device system comprised of a first element connected to a barrel muzzle and has an outer recess, and a gas seal element forward of the recess. The device body has a bore configured to sealably receive the gas seal element. The device body has a plurality of radial passages and a plurality of balls each received in one of the respective radial passages. The collar encircling the device body and movable axially between a released position in which the balls are free toward a radial excursion for removal of the body from the first element, and a secured position in which the balls are biased into the outer recess of the first element.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional PatentApplication No. 62/962,265, filed on Jan. 17, 2020, entitled“Quick-Detach Suppressor Adapter”, which is hereby incorporated byreference in its entirety for all that is taught and disclosed therein.

FIELD OF THE INVENTION

The present invention relates to firearm suppressor attachment methods.It comprises a spring-loaded quick-detach fitting to affix thesuppressor to the muzzle of a firearm.

BACKGROUND AND SUMMARY

Existing sound suppressors products utilize a ratcheting system that isscrewed onto the muzzle device.

This system is slow and complex, making it difficult for the user toattach a sound suppressor to a muzzle device.

The above disadvantages are addressed by a muzzle mounted device systemcomprised of a first element connected to a barrel muzzle and has anouter recess, and a gas seal element forward of the recess. The devicebody has a bore configured to sealably receive the gas seal element. Thedevice body has a plurality of radial passages and a plurality of ballseach received in one of the respective radial passages. The collarencircling the device body and movable axially between a releasedposition in which the balls are free toward a radial excursion forremoval of the body from the first element, and a secured position inwhich the balls are biased into the outer recess of the first element.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

The Adapter Body is cut from a round billet. A total of (4) lathe cutsare required: One to create the Upper Lug, another to create a recessfor the Disassembly Ring, one to cut the Suppressor Attachment threads,and last to create the Inlet Chamfer. The Adapter Body is then drilledaxially to create the central channel and twice cross-drilled at 90° tocreate the Ball Bearing channels. Last, the Ball Bearing recesses arechamfered by widening the channels through drilling operations alongeach recess's axis.

The Sleeve is cut from a round billet. First the Lower Lug is formed bymachining the billet from the lower end. Next, the Bearing Ramp ismachined from the upper end with (4) cuts. These cuts create twointerior flat surfaces and two interior sloped surfaces. The BearingRamp is comprised of the two sloped surfaces and their intermediate flatsurface.

The Disassembly Ring is cut from pipe stock and notched into a “C”shape. Expanding pliers are used to flex the Disassembly Ring between alarger radius and a smaller radius. When stretched to its larger radius,the Disassembly Ring fits between the Adapter Body and the Sleeve. Atits smaller radius, the Disassembly Ring fits into the Disassembly Ringrecess.

The Barrel Adapter is cut from a round billet. First it is throughdrilled axially and then the Barrel Threads are cut into the innersurface, at one end. The outer surface of the Barrel Adapter has threerings machined away, creating grooves for the Gas Rings. Finally, aBearing Groove is cut around the Barrel Adapter, matching the radius ofthe Ball Bearings.

A set of (4) Ball Bearings are placed into the Adapter Body's BallBearing recesses. The Sleeve slides upward from below the Adapter Bodyand the Sleeve's Bearing Ramp holds the Ball Bearings in place. TheSleeve Spring is inserted over the Adapter Body and rests against theLower (Sleeve) Lug. Expanding pliers are used to stretch the DisassemblyRing to its larger radius. It slides over the Adapter Body, and pressesagainst the Sleeve Spring. The Sleeve Spring is then graduallycompressed by the Disassembly Ring, which eventually falls into theDisassembly Ring recess, and returns to its smaller radius. TheDisassembly Ring holds the Sleeve Spring in place in the QD SuppressorAdapter's now assembled state.

Ensure firearm is unloaded, prior to attaching the QD SuppressorAdapter.

The Barrel Adapter is threaded onto a gun barrel and (3) Gas Rings areplaced into their grooves. Ensure the gaps in the Gas Rings are notaligned.

Thread the top of the assembled QD Suppressor Adapter into a suppressor.Compress the Sleeve Spring by sliding the Sleeve away from thesuppressor and insert the Barrel Adapter through the Inlet Chamfer. Oncethe first Gas Ring has passed the Ball Bearings, release the pressure onthe Sleeve Spring, and continue inserting the gun barrel until the BallBearings land in the Bearing Groove. The Sleeve will return to itsoriginal position and the Adapter will lock onto the Barrel Adapter.

Ensure firearm is unloaded, prior to disassembly. Allow the Suppressorand QD Suppressor Adapter to cool, prior to handling.

To remove the QD Suppressor Adapter from the firearm, compress theSleeve Spring by sliding the Sleeve away from the suppressor. Pull theSuppressor and Adapter away from the Barrel Adapter to remove it fromthe gun. Last, unscrew the Suppressor from the QD Suppressor Adapter.

To disassemble the QD Suppressor Adapter, use expanding pliers tostretch the Disassembly Ring to its larger radius, until it is pushedout of the Disassembly Ring recess by the Sleeve Spring. Place thedevice on a flat surface, with the Inlet Chamfer down and remove theAdapter Body from the Sleeve. Be careful to ensure the (4) Ball Bearingsfall out of the Adapter Body and into the Sleeve. The Sleeve Spring andBall Bearings will now fall loosely out of the Sleeve.

Clean the device regularly with the firearm. Store the device in a dryplace.
